Investigators say Rehma Sabir was unresponsive when she was brought to Boston Children’s Hospital January 14.

Doctors there said she was suffering from hemorrhaging and swelling of the brain and also had multiple bone fractures that were healing. She was declared brain dead January 16.

Authorities say Brady was caring for the child at a home in Cambridge and was the only person with her when the injuries occurred.

In court Tuesday, prosecutor Katharine Folger said she expects the charges to be upgraded to homicide.

Brady’s attorney Melinda Thompson said her client has been a nanny for 13 years and never had any incidents. They claim the child has traveled a great deal and that “anything could’ve happened” during those visits overseas.

While her criminal record may be clean, this isn’t Brady’s first run-in with the law.

In 2005, a man took out a restraining order against her after a bar fight.

In 2007, she faced an assault charge after another bar brawl. That charge was later dropped because the victim wouldn’t testify.

In 2012, a woman took out a restraining order against her.

Two days before the baby’s death, four separate loud noise complaints were made.

“I wouldn’t leave her watching my dog for an hour,” said neighbor Tom Collins who filed the noise complaints. “She’d just go off the hinges from like zero to sixty in like two seconds.”

On Tuesday, the US Immigration and Customs Enforcement agency said Brady entered the United States from Dublin, Ireland on Aug. 11, 2002, as part of the Visa Waiver Program that allows visitors to stay in the United States for 90 days without a visa.
